That is crazy; I did not even think about that. LOL. Yea, players in PvP will maybe spend 2-3 seconds in blizzard, which means each tick is going to do less than it previously did in 11.0.7 with the 40% 11.1 note updates. Shards also cannot crit, so its effective DPS is really bad. Unless they purposely stand in it to break CC for more than 8 seconds, which is also a game design flaw. In PvP, “Blizzard” was always a tool to get players out of stealth or prevent them from re-stealthing, so channeled low damage makes perfect sense from a competitive standpoint. Try finding someone hiding in shadowmeld when blizzard has a 6-second cooldown and is not channeled; you could blizzard in their general direction and never find them until Eye spawns. LOL. Channeled was not this way. It needs to be channeled like it was or back to lasting 8 seconds. Big Yikes. Retail generally feels like it is at the end of its life these days.
Just going to leave this here; hopefully one of their Frost Mage PvP developers picks it up, but I doubt they will.
